AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON KY
753 AM EDT TUE APR 5 2016

.UPDATE...
ISSUED AT 745 AM EDT TUE APR 5 2016

HOURLY GRIDS HAVE BEEN UPDATED BASED ON RECENT OBSERVATIONS AND
SATELLITE DATA. DRIER AIR IS WORKING INTO THE REGION AND THE
STRATOCU IS STARTING TO SCATTER OUT OF THE CENTRAL AND EASTERN
PART OF THE AREA.

&&

.SHORT TERM...(TODAY THROUGH WEDNESDAY)
ISSUED AT 400 AM EDT TUE APR 5 2016

THE PERIOD BEGINS WITH A TROUGH EXTENDING FROM EASTERN CANADA
SOUTH INTO THE EASTERN CONUS. IN BETWEEN THIS TROUGH AND A
SHORTWAVE MOVING THROUGH THE ROCKIES IS A SHORTWAVE RIDGE
EXTENDING NORTH FROM NORTHERN MEXICO. SFC HIGH PRESSURE IS
CURRENTLY BUILD INTO THE OH VALLEY REGION AND APPALACHIANS...BUT
STRATOCU PERSIST IN NW FLOW ALOFT. THERE HAVE ALSO BEEN SOME WEAK
RETURNS AT TIMES ON REGION RADAR DATA WITH A SPRINKLE OR FLURRY IN
A SPOT OR TWO NOT OUT OF THE QUESTION. TEMPERATURES CONTINUE TO
FALL IN COLD ADVECTION PATTERN WITH THE COLDEST READINGS IN THE
NORTHWEST...THE SOUTHWESTERN PART OF THE AREA THAT HAS EXPERIENCE
THE LEAST CLOUDS AND ELEVATIONS ABOVE 2500 FEET WHERE READINGS ARE
BELOW 30 DEGREES.

THE 850 MB TEMPS WILL BOTTOM OUT ACROSS THE AREA AROUND DAWN ON
IN THE -6C TO -11C RANGE. SFC TEMPERATURES ACROSS THE REGION
SHOULD DROP TO OR BELOW THE FREEZING MARK AT THAT POINT. HEIGHT
RISES AND THE SFC HIGH BUILDING IN SHOULD LEAD TO SKIES CLEARING
OUT THIS MORNING...WITH MOSTLY SUNNY SKIES FOR MUCH OF THE DAY.
HOWEVER...WITH THE COLD AIRMASS IN PLACE...HIGHS WILL END UP
NEARLY 15 DEGREES BELOW NORMAL FOR THIS TIME OF YEAR. DEWPOINTS
SHOULD ALSO DROP...DOWN INTO THE TEENS...SO RH WILL BOTTOM OUT
NEAR OR BELOW 25 PERCENT IN MANY LOCATIONS. HOWEVER...WINDS SHOULD
BE ON THE LIGHT SIDE.

THE AXIS OF THE SHORTWAVE RIDGING WILL MOVE EAST OF THE AREA
TONIGHT...WITH THE SFC HIGH ALSO DEPARTING TO THE EAST. THIS WILL
BRING AN INCREASING SOUTHERLY GRADIENT LATE TONIGHT AND INTO THE
DAY ON WEDNESDAY AS THE SHORTWAVE TROUGH MOVES TO THE GREAT LAKES
MS AND OH VALLEY REGIONS ALONG WITH THE CORRESPONDING SFC SYSTEM.
THIS WILL BEGIN TO SET THE STAGE FOR A DEVELOPING RATHER DEEP
EASTERN CONUS TROUGH BY THE EARLY PART OF THE LONG TERM PERIOD.

VALLEY LOCATIONS ACROSS THE EASTERN TWO THIRDS OF THE AREA SHOULD
DECOUPLE GIVEN THE DEGREE OF DRY AIR ANTICIPATED AND WEAKER
GRADIENT FOR THE FIRST HALF TO TWO THIRDS OF THE NIGHT. SOME
LOCATIONS MAY EXPERIENCE LOWS CLOSER TO 6Z OR 9Z OR PRIOR TO DAWN
AS THE GRADIENT INCREASE. COOP MOS GUIDANCE AND DEWPOINTS SUGGEST
LOWS IN MANY OF THE VALLEYS IN THE EASTERN TWO THIRDS OF THE AREA
LIKELY DROPPING INTO THE MID TO UPPER 20S. SOME VALLEY LOCATIONS
COULD EXPERIENCE 8 OR MORE HOURS BELOW FREEZING. RIDGETOPS SHOULD
NEAR OR TOUCH FREEZING...BUT PROBABLY NOT FALL BELOW FREEZING. A
FREEZE WATCH HAS BEEN ISSUED FOR TONIGHT.

THE DRY AIRMASS WILL BEGIN TO MODERATE ON WEDNESDAY...BUT
TEMPERATURES SHOULD ALSO WARM WELL INTO THE 60S. MIXING SUPPORTS
MIDDAY TO AFTERNOON GUSTS ON WEDNESDAY IN THE 25 TO 35 MPH RANGE.
RH THOUGH SHOULD BOTTOM OUT NEAR 25 PERCENT IN THE SOUTHEASTERN
PART OF THE AREA...LEADING TO AN ENHANCED FIRE DANGER AS FUELS
REMAIN ON THE DRY SIDE. THIS THREAT HAS BEEN INCLUDED IN THE HWO.

.LONG TERM...(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 408 AM EDT TUE APR 5 2016

...HARD FREEZE EXPECTED FRIDAY NIGHT/SATURDAY NIGHT...

AN UPPER LEVEL TROUGH WILL SET UP OVER THE EASTERN CONUS FOR THE
LONG TERM PERIOD. THIS WILL LEAD TO EVEN COLDER TEMPERATURES AND SNOW
CHANCES LATE IN THE WEEK. TEMPERATURES IN THE LOW AND MID 20S ARE
EXPECTED BOTH FRIDAY AND SATURDAY NIGHTS WITH SOME SPOTS POSSIBLY
MAKING IT INTO THE TEENS BY SUNDAY MORNING. THIS WILL SET UP A
DANGEROUS FREEZE FOR MUCH OF THE AREA...PUTTING FRUIT TREES AND
SENSITIVE PLANTS IN DANGER.

THE PERIOD WILL BEGIN AS A LOW PRESSURE SYSTEM CROSSES THE OHIO
VALLEY LATE WEDNESDAY AND WEDNESDAY NIGHT. DECENT MOISTURE ALONG
WITH AMPLE UPPER LEVEL FORCING SHOULD ALLOW FOR WIDESPREAD COVERAGE
OF RAIN AS THE SYSTEM PUSHES THROUGH THE AREA. BEST LOW LEVEL
FORCING WILL STAY NORTH OF THE AREA...AND LIKE MANY RECENT
SYSTEMS...DRY AIR IN PLACE MAY EAT AWAY AT THE PRECIP AS IT SPREADS
INTO THE AREA...DECREASING THE TOTAL QPF EASTERN KENTUCKY MAY
RECEIVE. MODEL QPF HAS BEEN OVERDONE WITH MANY OF THE RECENT
SYSTEMS...SO WE MAY NOT END UP WITH AS MUCH RAIN AS MODELS HAVE
ADVERTISED. A QUICK MOVING SHORT WAVE WILL SWING DOWN INTO KY BEHIND
THE DEPARTING SYSTEM THURSDAY EVENING...KEEPING PRECIP CHANCES IN
THE FORECAST. THIS SHORTWAVE WILL DEEPEN THE TROUGH AND ALLOW FOR
ANOTHER SURGE OF COLD AIR FOR THURSDAY NIGHT. FINALLY...ANOTHER
SHORTWAVE WILL DIVE SOUTHEAST LATE FRIDAY...BRINGING TEMPERATURES 20
DEGREES BELOW NORMAL TO THE AREA. 850MB TEMPERATURES ARE PROGGED TO
DROP TO AS LOW AS -15C BY EARLY SATURDAY MORNING. THIS WILL SEND SFC
TEMPS INTO THE 20S...AND WITH A SFC HIGH SETTING UP OVER THE REGION
SATURDAY NIGHT...TEMPS COULD DIP INTO THE UPPER TEENS BY SUNDAY
MORNING. FORTUNATELY...A WARM UP WILL BE ON TAP FOR MONDAY AS WINDS
TURN BACK TO THE SOUTHWEST AHEAD OF THE NEXT LOW PRESSURE SYSTEM.

PRECIPITATION CHANCES WILL REMAIN IN PLACE THROUGH MUCH OF THE
EXTENDED PERIOD....WITH RAIN REMAINING THE DOMINANT PRECIP TYPE
THROUGH FRIDAY EVENING. WE WILL THEN SEE THE TRANSITION OF RAIN TO
SNOW FRIDAY NIGHT AS COLD AIR SETTLES IN. SOME LIGHT SNOW
ACCUMULATIONS ARE POSSIBLE IN THE HIGHER TERRAIN FRIDAY NIGHT INTO
SATURDAY MORNING. ELSEWHERE...WARM GROUND TEMPERATURES SHOULD LIMIT
ANY IMPACTS AND SNOW ACCUMULATIONS. SNOW CHANCES WILL COME TO AN END
SATURDAY EVENING AS HIGH PRESSURE BUILDS INTO THE REGION. DRY
CONDITIONS WILL BE ON TAP FOR THE REMAINDER OF THE PERIOD.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z WEDNESDAY MORNING)
ISSUED AT 750 AM EDT TUE APR 5 2016

SOME STRATOCU MAINLY IN THE VFR RANGE...WITH A BIT OF MVFR NEAR
THE VA BORDER LINGERS ACROSS THE REGION. THIS SHOULD SCATTER OUT
OVER THE FIRST 3 OR 4 HOURS OF THE PERIOD AND LEAVE BEHIND VFR
CONDITIONS AS HIGH PRESSURE TAKES CONTROL. WINDS SHOULD AVERAGE
10KT OR LESS THROUGH THE PERIOD. WINDS ALOFT WILL BE INCREASING
AHEAD OF A COLD FRONT LATE IN THE PERIOD...AND SOME LOW LEVEL WIND
SHEAR WILL BE POSSIBLE AFTER 8Z.
